"A Murder of Crows"
Often dismissed by humans as a general nuisance, crows are social creatures that chat with each other in at least two different dialects and as many of 250 distinct calls. They mate for life, mourn their dead and raise their young for up to five years. The show reports on research by University of Washington professor John Marzluff, as well as work at New Zealand's University of Auckland and Austria's Konrad Lorenz Institute.G
